BOX GAR noon Application filed September 2,1930. 3 Serial no. 4793155 I to provide positive means to prevent the entrance of dust, dirt and rain and to provide means making it impossible for the car door to be pried open even for a short distance, as it can with conventional door locking means where small boxes can be removed from the car without mutilating the lock and seal. My invention is to provide a closure and locking device' wherein the door cannot be moved away from the wall or the door aperture without destruction of the seal. My invention is illustrated as applied to a railroad box car, more or less diagrammatically in the accompanying drawings wherein; p Figure 1 shows the door in the closed position;

Fig. 2 shows the door in open position; Fig. 3 is a section on an enlarged scale along the line 33 of Fig. 1; Fig. 4: is a section on a further enlarged scale along the line 41-44; of Fig. 2; a Fig- 5 is a section on an enlarged scale along the line 55 of Fig. 1;

Fig. 6 is a section on an enlarged scale along the line 66 of Fig. 1. r

A is the supporting frame 01"- a box car carrying a floor A above which rise supporting stringers A to support a roof, A Siding A is carried by the stringers A 011 the 40 side therefor, and there is a door opening as indicated at A in Figure 2. This door opening is provided at the top with a lintel A which projects outwardly from the sheathing A slightly beyond the stringers Bolted or screwed to the siding A immedi- V ately above thelintel A is a track B. This I track has its inner flange bolted or screwed to the siding A This track resting on the top of the lintel extends outwardly thereheyond and the flange B overhangs the lintelpthere being a sufficient clearance between the flange and the lintel for the door B 'which may be, of ;wood or metal or a composite as thejcase maybeJ B is a hanger extending upwardly from the door enclosingthe flange B 0verlying; the "outer edge of the track-B and carry 'ing a plurality of rollers B which engage such track'so as to provide aroller support from which the door'hangs, nospecial track being" needed, andthus 'a positive interlock. is provided throughout the entire extent of thetop oftheid'o'or between the door andthe lintel and alsoproviding a water-tight closure between the lintel and the door top.

Cisa'front door;jam-projecting outward- 1y from the siding a distance substantially equal to the lintel and reinforced'by'means of a Z-barC I The lintel C on the side adja- 1 cent the door projectssimilarly to the lintel C and is similarlyreinforced by a Z-bar C Projecting outwardly from the lintel C and overhanging it is'an angle bar Ct having a flange C spaced from the jam C sufficiently I to permit the door B to enter the space be- 3 tween it and the jam thereby providing along the front edge of thedoora positive interlock from top tofbottom as well-as a'water proof closure. C are the usual brackets projecting upwardlyfrom thecar well spaced there 33 from to permit passage of the dooras it slides into and out of register with'the door open. and adapted to hold the door at all times'in proper position. These brackets take the form of short Z-bar elements extendingalong theent'ire path of travel of the door'just as 'does the door B. C is the usual handle at thebot-ton of the door by which the door may I be" opened or'closed. I Q v j.. D is a hinge plate rigidly attachedto the 96 outside of the Z-bar carrying a hinge pin D spaced within the" contour of thej am and thus behind the door B? in all positions. Pi'vo'ted on-this pin'D is an angle bar D which in the position shown in Figure 8, en- Q5 may be withdrawn. D is a strap bolted or riveted tothe siding andhavingpivotedthereon a link D which terminates in an eyelet D adapted to :be engaged by the lock pin i 5 ID slidable in the stapleD on the pivoted angle bar or looking jam D This pin D is slotted atD to take the usual car seal-D which-insures that the parts remain in locked position until the seal is destroyedbecause V 10 without its destruction the pin D cannot be withdrawn. As long as the'pi-n D i s not withdrawnvthe member ID acts as a strut or V brace holding the jam D in the position I? shown in Figure 3 and closing the rearmost 1 edge of the door to positively prevent-travel or longitudinal movement of the door as this a. f cannotftake place without destruction of the .lock which owing to its great weight and strength is exceedingly diflicult. If this look is ,appliedto a car ofthe outside sheathed type then the/sheathing, will be cut away to form :a pocket to contain the members D D? and 1). Aside from that the locking 1 action willbe substantially the same.- In

'25 order tohold the door'in the open position 'whenqthatxis desired theanchor plate E is Iprovid-ed on the jam C Pivotedv on this anchor plate is alink E andpivoted on it is a hasp link E which hasp link is provided with an eyelet E adapted when shown in the position in Figure 2, to be interlocked with the hasp E. The locking pin E locks V the car in open position and prevents its bein shaken out of place when the car'is moved when the door is open. I'claim:- 7 7 In combination'wi-th a box car and sliding door therefor, means for holding the door in position spaced from the outer wall of the Q car, a lock for the door comprising an angle extending substantially the entire height of the door pivoted along a vertical axis and adapted when incthe inoperativeposition to be enclosed between'thecdoor and the car, the

# angle being :pivotedto the car'i'mmediately behind the door, a lock link pivoted .onthe car adapted to be enclosed behind the, door, the relation betweenthe angle and the link being such that when the doorfis closed and {5 the angle is rotated into engagement with the rear edge of the door, it overlies the outer wallthereof, and the link being adapted-to abut on the angle, means for locking the link 7 and angle in fixed relation to hold the angle againstrotation and form a permanent lock for the door.
